| Abstract: | The eco-environmental susceptibility is to demonstrate the reaction of a ecosystem under the same influences of the human
activity. It comprise many influencing factors which have a complicated relation to the eco-environmental susceptibility.
In this paper, the Analysis of Hierarchy Process (AHP) is used to determine the weight of each factor to the eco-environmental
susceptibility through analyzing the relationship between human activity and environmental deterioration. And the weighted
summation method is used to calculate the eco-environmental susceptibility of different divisions in Yulin region. The result
shows that the loess hilly and gully area is more subjective to deteriorating eco-environment than the desert area because
of the strong human activity and severe soil erosion.
